On the morphology and life-history of a form of gloeocapsa showing some new stages

Summary A new variety of Gloeocapsa, G. crepidinum Thuret var. ghazipurensis n. var., has been isolated from enrichment cultures of paddy field soils of Ghazipur, Uttar Pradesh, India. The alga has been studied in detail. The form is especially interesting since it showed certain growth-stages recorded in G. alpina Naeg.The authors are thankful to Rev. Dr. H. Santapau for rendering the Latin diagnosis of the new variety.
